"It was the only thing I really bottled in," Kylie shared. "I don't bottle in a lot of things and I feel like my family was a little upset about that. But I got through it and now I almost like it a lot better, honestly."

The youngest Jenner sister appreciates that there is no longer "a huge secret" in her family. "We talk about makeup and clothes. We bond a lot more," Kylie said of her relationship with Caitlyn. "I’ve honestly known about it for a really long time and we actually caught him dressing up as a girl, when my sister and I were like six and seven maybe. So we've known for a while that there was something, but it was never talked about."

"She's really living her authentic true self," Kylie added. "She's the same exact person. She just looks different I guess."

Like Caitlyn, the reality star wants to lead by example, and hopes to be a role model for her peers.

"I want to be someone from my generation [who is] an example, because I think that's so awesome," Kylie said. "I think that other girls and boys my age will maybe see that I'm so accepting and be accepting of other people too."

To this end, Kylie recently began an online anti-bullying campaign called I Am More Than. She hopes to use her platform as a celebrity to "hopefully inspire my followers" to be open about their experiences with getting bullied and share a message of hope and peace.
